What was supposed to be a normal train ride in Chicago for Twitter user @raresoulx turned out to be the complete opposite. According to @raresoulx, a drunken white passenger on the train repeatedly called an elderly black man the n-word for 15 minutes. After being verbally accosted, the unidentified black man took matters into his own hands, literally. And it was, of course, captured on video.
